Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Lenovo ZUK Z2 (Plus)'s battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

One of the biggest issues in the current Oreo ROMs is the mobile network standby drain.
People using the Pie alphas should report if it still exists or has been fixed, although I don't see any new baseband and hence the chances of latter are less.

I think I'm going to flash a really old stock ZUI for the firmware and then flash the legendary AEX 4.6 Nougat. That seems to be the only way forward to get some decent battery life and stability.

You could also install the viper os 3.0 final build but the problem with that is that it doesnt have the cameraapi 2 enabled on that because of that the google cam wouldnt work. The photos taken by the google cam and stock cam differ in the quality by a huge margin to be ignored

Which ZUI you would flash? Stock Indian 2.5 or the Chinese ones?

I ended up dowloading ZUI 2.0.093 Indian for qfil and ZUI 2.5.104 stock recovery zip (qpst one for this wasn't downloading for me).
I flashed ZUI 2.0 via qfil successfully, and received a small oTA to 2.0.133, and then decided to flash 2.5 via recovery, but failed to get it work. Anyways, decided to go ahead and unlock the BL and then I ended up flashing only the baseband from Indian 2.5.099 (data quota restrictions ).
After that I flashed the last build of AEX 4.6, used it for a day and the standby drain was not like a drain overthere. Unless I did not use hotspot, it wouldn't show up in top 5.
Few hours later, got a notification for a rebased release of Jaguar oreo, and couldn't resist from trying it out. Initial impressions were great, but slowly the standby drain started creeping in, and within a few hours it rose to the top. Luckily I made a nandroid backup of the AEX 4.6 Installation which I reverted to last night.
I do miss the oreo features though

Developers should look around the way Oneplus 6T addressed the issue. Coz I heard, they almost fixed the issue in the new phone.

So does this problem exist for all android phones that are above android Oreo??? or is it just for our phones. The thing iam trying to understand here is that is it google that messed up android or is the developer that created the roms for our phone that messed up. Its actually funny how the phone uses more battery when the phone is not in use.:cyclops::cyclops:

Hmm that means that you wouldn't be able to use google cam that means a huge degrade in the picture quality

After creating a nandroid backup of fully loaded aex 4.6, I'm back to living on the bleeding edge. Going back to aex 4.6 wasn't as good in terms for battery performance Z I expected it to be.
Currently on october pixel exp pie and the latest gcam pixel3 mod and even the pixel 2 mods frequently crash the phone (kernel panic maybe) during HDR processing. Didn't have time for debugging so received a lot of frowning from family for missed shots and extended wait times but who cares as whatever gcam was able to shoot was unbelievable.
Would be moving to the latest AEX pie with 4.4 kernel soon as I have read that the new kernel will improve the battery life.

Hmm, is this issue specific to Oct build of PE Pie ROM ? Or you witnessed with earlier versions of PE too?

Battery life started decreasing after beginning of Android Oreo 8.1.
I'm using Viper Nougat Final + OSS Cam patch. I'm pretty happy with it.

Is updating firmware to zui 4.0 can solve draining problem

Which rom and baseband do you use ??

ZUI 5 GSI has very low standby drain and SOT is also really good between oreo roms. You can try it once.

mine was so bad
I lose 25-30 percent through the night everynight and, I just replaced my battery for 3 month.
i don't know what's going on.
Can any one recommend me some good battery rom please ?

The battery drain issues are solved
Guys iam happy to report that the battery drain issues are solved on latest build of bootleggers 4.0 rom
Here is a link to it

Battery drain on all custom roms

I'm new to Xiaomi mi max 32Gb. At the moment, I'm running MIUI 9 global 8.2.24 beta and the battery life is fantastic, 11 hours of SOT, but every time I flash a custom roms the battery drain is crazy, 5 hours of SOT. I have tried a couple of custom roms but it's always the same. I get about half of battery life in any custom roms. Is there something that I'm doing wrong

same as mew , more SOT in miui than Other non miui custom rom.

You should install:
-greenify:Restrict background apps activity
-app opsisable (location+keep phone awake+kee app in background) for all apps
-betterbatterystats:shows you what drains the battery
-run battery saver mode
-install custom kernel

when i first bought this phone and used miui i charge every 3 days. with custom rom and greenify, every day. so up to you. u want long battery or custom rom

Which costume ROM's?
Stable unofficial LineageOS (nijel8) out of the box gives 11~12h of SOT while stable global MIUI 9.5.2.0 gives 5 to 8 h SOT.
This is normal use without heavy gaming of course.

I tried stable unofficial lineageOs nijel8 and had only 5 sot, also tried pixel experience and was all the same with 5-6 sot then went back to MIUI 9 and I'm back to 11 sot

Well obviously you did something wrong. With more costume scheduler settings people where getting & up to 17h of SOT (but that whose with rather extreme approach) on unofficial LineageOS 14.1 with light usage all well documented on power/performance thread. Had a guy with similar problem as you around month ago, his problem turned out to be a binary leftovers from dirty flashes of different costume ROM's. After he did it properly thing's changed. The name of user whose arbitrarygrill, read couple of pages back.
https://forum.xda-developers.com/mi-max/development/rom-lineageos-14-1-t3529851/page436
& you can always get more with costume scheduler/hotplug script's. Prime concern whose to match good old MIUI 8.2 - 8.3 SOT out of the box but with much better performance & without MIUI limitations (background apps/services aggressive killing) which we achieved in all arias mostly by working on kernel which Xiaomi never did & it's a source of most firmware problems today. Fun part is that 90% of back supplementary settings & libs are the same today; Xiaomi uses CAF settings & libs across the board (same as our unofficial Lineage is) and unofficial LineageOS uses the vendor libs from MIUI aside from ROM (apps) side only general difference is the kernel for which I vouch that our works much better & is safer.

Kernel is already semi costume, only a couple of things are added that are really beneficial as FIOPS IO scheduler & are set as defaults.

Suggestions for stock android experience without using custom ROM ?

I wanted a stock android experience for notifications bar, dialer etc. without using custom rom. Any suggestions. Don't want to use any launchers and want the miui kind battery life.
Any suggestions please ?

I have heard custom rom SOT is very less when compared to the MIUI. So didn't find it very appealing. I there any way where i can get the same SOT as MIUI in the available custom ROM ?

Lmao, who lied to you bruh? I easily get 10 hours of screen on time with aosip. With havoc I got 13 hours once, but i had good coverage and I was reading ebooks on my phone. Besides masik I find Miui to be trash in battery life, i hardly get 8 hours of SOT. On masik 4.1 i get between 8 and 10 hours. Of course it depends on your usage, but usually you can get more than 8 hours on most aosp roms.
Edit: i used to get around 12 hours of sot with miui 9, but neer on miui 10

Use Havoc OS 2.0 [Official] and flash basic kernel in it.. been using that combo for over a month and it gives nearly 9 hours of SOT

Android Oreo in 2019

Hello everyone,
Just curious to know if we have Oxygen os builds available for Oreo in 2019. Would like to rollback to Oreo but don't want to lose android security patches.
Android pie is working fine. But really miss the brightness levels and camera was better in nougat and Oreo compared to pie. Battery was the top in nougat easily got 6-7 hours screen on time with enough battery left for the day and with Oreo it was the best 8-8.5 hours.
Not complaining about pie. Can get through the whole day with moderate use and 20-30% left in evening. Just sharing my experience so far with 5t.
I would like to try nougat or Oreo if there are any versions available with latest android security patches.
Apologies if this has been already asked somewhere and answered. I went across XDA and OnePlus forums, Plz let me know if anyone is running Oxygen os with nougat/Oreo at the moment. Thanks!!

I dont see any decrease in battery life in pie. More likely your battery degenerated over time or some apps or background services drain it.
Go hunting for it with logcat or betterbatterystats

Try custom ROMs

Yes...custom roms are totally worth it, Since I have multiple work apps installed at the moment. a bit concerned on how they will work under root. Just sharing my usage logs with a comparison between Oreo and pie
The first set of screenshots are from moderate day usage in Oreo back in 2018 which has mixed usage of social apps and gaming
The second usage is from current stable 9.0.6
Not sure if everyone is getting similar battery life between Oreo and pie in moderate usage throughout the day.
I feel the 10-15% difference with battery left at end of day cause a big change still I get to manage throughout the day in pie.
Compared to Oreo from these random usage screenshots, pie is getting worse day by day. Maybe it's the battery that gets degraded over time or its the overall phone hardware that runs round the clock for us
I have this feel almost with every device, Samsung galaxy 5, Xperia neo v and also back in opo. Android kitkat had best battery and lollipop had a moderate and with marshmallow it got worse.
Just sharing my opinion and also curious to know if y'all out there feel the same.
Edit : Would like to add all these usage were taken in locked bl running unrooted

No need for root , just flash a custom rom and then enjoy ,for me comparing to Oreo pie has good SOT , AND im a heavy Gamer so cant help with battery stats :silly::laugh:
Still many custom ROMs works good in SOT with a custom kernel too.

Hmm yeah.. planning to give it a try. Been sticking with stock unroot most of times since I got 5t. Had it unlocked and under root for few weeks back in January due to shutter sound bug. Since it got fixed moved to stable.
I could see many custom roms are available to try.
Any tips on choosing custom rom, I mainly look for Oxygen os camera and good battery. How's OOS open beta holding up compared to stable pie in terms of battery.

Best Stable ROM

Hi!
can anybody confirm which android version is more stable & featurefull among 10-12?
I'm currently using Android 12, but i want more stability & fluidity in my device.
Thanks in advance!

I personally thought that Android 10 was better than Android 11 which was noticeably slower and while Android 12 is buggy, the battery life is way better than it was previously so I just stick with 12. Getting over 4 hours SoT from 65% of the battery (I charge at 20%, take off charger at 85%) is great, and on days I actually charge to 100% because I know I'll be out of the house, 7 1/2 to 8 hours is possible.

I'm running stock FW, Android 12, always updated. And, I just notice I didn't received updates since 5 october. Well, end of life of my Pixel 3.
I can confirm battery drain, but for security reason, I stayed with stock updated.
Now, it's another story.
Thanks for the infos @EtherealRemnant.
Any advise for any Rom or you stay on Stock?
Sorry OP, if I disturb your post with my demand or if it's out of subject.
Thanks
